Necessity and Method of Direct Experiment on the Invariant Principle of Light Speed

摘要

He-Ne gas laser is intermittent by electro-optic shutter, and the light emitted is divided into three optical paths, A, B, and C by semi-reflective partial reflector, and then reflected by rotating mirror to change its speed. The C light is reflected back to the fixed mirror to return the speed to the original, and then the speed difference progresses by a certain distance with the A light affected by the mirror motion, and then overlaps with a partial reflector to detect the phase difference. Experimental method to determine whether it is affected by the exercise of the body.
